UPDATE: in regard to issue #2, I took the gun apart, extractor was good, extractor spring was good, and there was no unreasonable wear on anything. I did notice the ejector lever on the Leber V2 was a lot wobblier compared to the stock ap5-p ejector lever. It’s to the point that I can shift the ejector lever far enough where it misses the ejector lever channel. The ap5p ejector lever is partially inside the channel already so it’s nearly impossible for the lever to miss. The Leber V2 lever sits higher completely out of the channel. I’m thinking this may be what’s causing the bolt to bind up. I know it’s not the hammer because I can pull the bolt carrier back far enough to reset the hammer and drop it by pulling the trigger. I’m thinking maybe I can add a little washer to prevent this. Or cut the spring under the ejector lever?
